我国自８０年代以来借鉴国外经验开始研究用爆炸法消除中厚板的焊接残余应力。该方法已于１９８６年通过中国科学院鉴定，在大型球罐上有应用，在水电站压力钢管也有少量应用。经慎重地通过室内与原型试验后，在清江隔河岩工程大型钢管上大规模采用，实践证明，技术上是成功的，为大型钢管消除焊接残余应力，提供了有价值的工程实例 Since the 1980s, our country has learned from foreign experience and started to study the use of explosion method to eliminate welding residual stress in plate. The method has been identified by the Chinese Academy of Sciences in 1986, has applications in large spherical tanks, and there are also a few applications of pressure pipes in hydropower stations. After careful examination through indoor and prototype experiments, the Qingjiang Geheyan large-scale steel pipe on the large-scale use of practice proved to be technically successful for the large-scale steel to eliminate welding residual stress, providing valuable examples of the project
